Commitments and Contingencies	7. Commitments and Contingencies Commitments Aldoxorubicin We have an agreement (the “Vergell Agreement”) with Vergell Medical (formerly with KTB Tumorforschungs GmbH) (“Vergell”) for the exclusive license of patent rights held by Vergell for the worldwide development and commercialization of aldoxorubicin. Under the agreement, we had to make payments to Vergell upon meeting certain clinical and regulatory milestones up to and including the product’s second final marketing approval. However, those payments are no longer required since the intellectual property acquired under the Vergell Agreement has now expired. We accrued $316,000 that we believe is owed prior to the expiry of the intellectual property. This amount was outstanding both for the six-month periods ended June 30, 2023 and June 30, 2022. Arimoclomol The agreement relating to our worldwide rights to arimoclomol provides for our payment of up to an aggregate of $3.65 million upon receipt of milestone payments from Orphayzme A/S. On May 31, 2022, Orphazyme announced that it had completed the sale of substantially all of its assets and business activities for cash consideration of $12.8 million and assumption of liabilities estimated to equal approximately $5.2 million to KemPharm (the “KemPharm Transaction”). KemPharm is a specialty biopharmaceutical company focused on the discovery and development of novel treatments for rare central nervous system (“CNS”) diseases. As part of the KemPharm Transaction, all of Orphazyme’s obligations to LadRx under the 2011 Arimoclomol Agreement, including with regard to milestone payments and royalties on sales, were assumed by KemPharm.

Innovive Under the merger agreement by which we acquired Innovive, we agreed to pay the former Innovive stockholders a total of up to approximately $18.3 million of future earnout merger consideration, subject to our achievement of specified net sales under the Innovive license agreements.

The Company is occasionally involved in legal proceedings and other matters arising from the normal course of business. On November 30, 2022, Jerald Hammann (“Hammann”) filed a complaint (the “Complaint”) against the Company, Mr. Caloz, and Mr. Kriegsman (together, “Defendants”) in the Court of Chancery of the State of Delaware, alleging various violations of a Cooperation Agreement, dated August 21, 2020, by and between the Company and Hammann. The Complaint alleges breaches of a provision limiting the Board’s ability to effect discretionary compensation and a non-disparagement provision. The Complaint further alleges a breach of a purported implied obligation that the Company disclose various internal records to Hammann. Defendants believe the Complaint is wholly without merit and have moved to dismiss the Complaint in its entirety. Hammann has opposed the motion to dismiss and briefing of the motion is ongoing. Defendants intend to litigate vigorously against Hammann’s claims. The Company evaluates developments in legal proceedings and other matters on a quarterly basis.

COVID-19 is expected to remain a serious endemic threat for an indefinite future period, and may continue to adversely affect the global economy, the companies which we are working to develop and commercialize our products, such as ImmunityBio and KemPharm, and we are unable to predict the full extent of potential delays or impacts on our business, and operations. The extent to which the COVID-19 endemic and its ongoing effects, including but not limited to supply chain issues, global shortages of supplies, material and products, volatile market conditions and rising global inflation may impact our business and prospects will depend on future developments, which remain uncertain and cannot be predicted with confidence.
